Which best identifies a function analogy ?
a. dog: cat: : cat: mouse
b. yellow: bright: : one: little
c.ugly: pretty: : tall: short
d.car: drive: : bike: ride

As the name itself says, a function analogy compares the functions that two or more things may have. 
Having that in mind, the correct answer is D. car:drive::bike:ride.
The function of a car is to drive, and the function of a bike is to ride. The other options are analogies, just not function analogies.
